GRAIN-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 707,251, dated August 19, 1902. Application filed September 20, 1900. Serial No. 30,587. (No model.)

To @ZZ whom t may coz/werft:

Be it known that I, CHRISTIAN OTTO, a citizen of the United States, residing at Hastings, in the county of Cambria and State of Pennsylvania, have invented a new and useful Grain-Separator, of which the following is a specification. y

The invention relates to improvements in grain-separators.

The object of the present invention is to improve the construction of grain-separators and to provide an exceedingly simple and inexpensive one adapted to be conveniently operated by an ordinary farmer to enable him cordance with this invention.

view, partly in section. Fig. 3 is a detail sectional view illustrating the manner of mountingy the rotary cylinder. Fig. 4 lis a detail sectional view illustrating the arrangement of the trough.

Like numerals of reference designate corresponding parts in all the figures of the draw ings.

1 designates a supporting-frame comprising a rectangular top portion 2 and sides 3A and 4, supporting the rectangular top portion and provided with bearing-recesses 5 and 6 for the reception of a rotary cylinder 7, which is arranged within the rectangular top portion of the supporting-frame.4 The sides 3` and 4, which form the supporting-legs, may be constructed in any suitable manner, and the rotary cylinder is provided with exterior circular ribs 8 aud`9, forming annular exterior tracks which are-received by groved rollersl 9, mounted on the sides 3 and 4 at the bearing-recesses thereof and projecting slightly above the curved bottoms of the said bearing-recesses. The grooved rollers or antifriction-wheels 9 are arranged in suit- Fig. 2is a plan able recesses, as clearly illustrated in Fig. 3 of the accompanying drawings, and the cylinder is confined inproper position on the said rollers orwheels by means of curved rods 10, extending over the top of the cylinder and having their ends secured to the inner faces of the sides and 4 at opposite sides of the rotary cylinder. VThe top portion of the frame is composed of side and end bars, and one of the end bars forms a'supportjor a hopper which is providedwith a depending spout 12,

extending into the cylinder at one end thereof. The hopper 11 is located above the horizontal top portion of the supporting-frame, and the. cylinder is provided with an annular flange 13, extending inward and preventing the grain from escaping at thatv end of the machine. The spout 12 of the hopper is preferably extended through the adjacent end bar of the rectangular top portionofthe supporting-frame and it delivers the grain upon the bottom of thecylinder. The cylinder is provided on its interior with indentations' or cavities 14, adapted to receive the small round grains of lcockle whichlie in the cavities or indentations andwhich are carried upward by the rotation of the cylinder and deposited in a longitudinal trou-gh 14a,'located at one side of the cylinder, as clearly illustrated in Fig.l 2 of the accompanying drawings. The troughiis provided at one .end with an arm' 15, which issecured to the lower face of the adjacent end bar of thersupporting-frame, and the other end of the trough, which is provided Vwith a spout 16, is supported by a bracket 17, extending laterally from the trough'and secured-to the adjacent side bar of the horizontal portion of the supportingframe. The spoutv is adaptedY to discharge thecockle intoa bag, box, or other receptacle, and the said cockie is carried along the .trough to the discharge end thereof by a ro tary spiral conveyer 18, located within the trough and extending longitudinally thereof, as clearly shown in Fig. 2. The cleaned grain is discharged from the cylinder into an inclined chute 19, secured tothe outer face of the side 3 of the supporting-frame and adapt- IOO ed to deliver the grain into bags or other receptacles. end with an exterior gear consisting of a-ring or band 20, provided with spur-teeth and The cylinder is provided at one meshing With a pinion 2l of a longitudinal shaft 22,Which is journaled in suitable bearings of the top portion of the supportingframe. The shaft 22 is provided at one end of the machine with a large pulley 24, adapted to receive abelt, and the other end of the shaft has a small grooved pulley 25 fixed to it and designed to be connected by a belt with a similar grooved pulley 27 fixed to the conveyer-shaft.

The separator may be driven by any suitable power, and owing to its great simplicity and cheapness it may be readily operated by the ordinary farmer and will enable him to clean his grain as it is required for sowing, milling, or for the market.

It Will be seen that the separator possesses great strength and durability, that it is easily operated, and that it is not liable to get ont of order. It will also be clear that it is effective in its operation and that it isadapted to readily separate the cockle from Wheat and rye and that the small grains of cookle will be carried upward in the cavities or indentations to the trough, While the grains of Wheat and rye will be rejected by such indentations or cavities and will pass out of the machine at the open end of the cylinder into the inclined chute. Should any grains of rye or Wheat lodge endwise in the small indentations or cavities, they will drop out of the same before they reach the trough and will not be carried into the latter.

What is claimed is-- l. In combination With a frame, supporting-rollers mounted thereon for revolution and having annular peripheral grooves, a revoluble cylinder supported on said rollers and having annular peripheral track-ribs engaging the grooves in the rollers, and curved rods secured to the frame, arched over and bearing on the cylinder, said rods preventing the cylinder from moving from the rollers and coacting with the respectively ribbed and grooved cylinder and rollers to prevent longitudinal movement of the cylinder on the rollers, substantially as described.

2. The combination of a frame, supportingrollers mounted thereon for revolution and having annular peripheral grooves, a revoluble cylinder supported ou said rollers and having annular peripheral track-ribs engaging the grooves in the rollers, curved rods secured to the frame, arched over and bearing on the cylinder to prevent the latter from moving from the rollers and to coact with the respectively ribbed and grooved cylinder and rollers to prevent longitudinal movement of lthe former on the latter, a gear 20 on said cylinder, a power-shaft 22 having its bearings on said frame and provided with a pinion engaging said gear, a pulley 25 on said powershaft, a iixed cockle-receiving trough extending longitudinally through the cylinder at one side thereof, a revoluble conveying-screw in said trough, having a shaft journaled in bearings in the frame and provided with a pulley 27, aud an endless belt connecting said pulleys 25, 27, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aiixed my signature in the presence of two witnesses.

CHRISTIAN OTTO.
